Dynamo Kiev defender Badr El Kaddouri is convinced they can shock Arsenal.
William Gallas grabbed a last-gasp equaliser to earn the Gunners a 1-1 draw in Kiev two months ago.
El Kaddouri, whose side are three points behind table-topping Arsenal, said: "We need to get something from the game and losing is not an option.
"It will not be easy but this Arsenal team does not frighten us.
"They are not as strong as in previous seasons and Theo Walcott's absence is a relief for our defence."
